Applications of Porous Silica
化妆品
Our porous silica can be used in cosmetic applications such as oil control pressed powders, soft focus loose powders, sunscreen products, and matte skin feel modifiers.
It is commonly used for sebum absorption, skin feel improvement, and pore blurring effects.
Industrial Adsorption and Catalysis
Porous silica can be used as an industrial adsorbent silica and catalyst carrier material.
Typical applications include heavy metal adsorption, VOC adsorption, and catalyst support systems.
Coatings and Inks
Porous silica is widely used in coatings and inks, including wood coatings, automotive coatings, and printing inks.
This is because it can provide matting agent performance, anti-settling performance, and scratch resistance.
These applications can improve adsorption efficiency and catalytic performance.
Benefits and Properties of Porous Silica
Improve Formulation Performance and Silica Applications
Porous silica helps improve the performance of coatings and inks.
It provides excellent matting agent efficiency and anti-settling performance.
These properties are important for maintaining product consistency and application stability.

Porous Silica vs. Fumed Silica – What Is the Difference?
The following are some key differences.
Source and Structure
Porous silica has a well-developed pore structure, including micropores, mesopores, and macropores.
Specific surface area and pore volume are its key performance indicators.
Fumed silica consists of aggregated nano-sized primary particles.
It has a non-porous or low-porosity structure.
Its primary advantages are thickening performance and thixotropic performance.
Adsorption and Controlled Release
The pore volume and pore size of porous silica can be customized.
It provides strong adsorption capacity and controlled release performance.
This makes it suitable for use as a carrier material and matting agent.
The primary function of fumed silica is rheology control.
Its adsorption capacity is relatively limited.
Absorption and Dispersion
Porous silica has a significantly higher oil absorption value than fumed silica.
It is more effective in applications requiring high adsorption capacity.
This means porous silica offers advantages in skin feel improvement, oil control, drug loading, and matting performance.
Choosing the Right Silica for Your Application
Silica: FAQ Guide
What you are describing is hard agglomeration — a common issue when the supplier cannot control primary particle size or allows particles to fuse during drying/storage.
Here is how we prevent this：
Controlled primary particle size：Our synthesis process ensures narrow particle size distribution.
No hard agglomerates：Our drying and packaging processes are designed to prevent particle fusion.
Dispersion test available：We can provide dispersion test reports for your specific resin system.
What you can expect：Our porous silica disperses easily with standard high-speed mixing — no additional milling required.No floating powder. No “fisheyes” or surface defects on your film.
Yes — we provide 1:1 seamless alternatives.

This is a common issue when the porous silica has particle size too large 或 poor refractive index matching with your base formula.
Here is why some porous silica causes chalkiness：
Large particles (>15 μm) scatter visible light, creating a white or hazy appearance
Poor dispersion leaves visible agglomerates that look like white specks
How we solve this：
| Issue | Our solution |
|---|---|
| Chalky appearance | Particle size D50 controlled at 5-10 μm — minimizes light scattering |
| White specks in pressed powder | No hard agglomerates — disperses evenly |
| Hazy finish in transparent formulas | Ultra-fine grade available (D50 <5 μm) for clear gels and serums |
